'ACETYLENEHGAS GENERATOR.

sirnorrtonrrroiv forming part of Letters Patent No. 689,1 1, dated December 17, 1901- Applioation filed February 18, 1899. Serial No. 706,033 (No model.)

To all whom it may concern.-

Be it known that 1, PAUL MARG-ULIES, engineer, of No.13 Tiraspolskaja, Odessa, in the Empire of Russia, have invented certain new and useful Improvements in Acetylene- Gras Generators, of which the following is a full, clear, and exact specification.

Thisinvention relates to that class of acetylone-gas generators in which the carbid is subjected to small quantities of water as the gas is needed for use, the supply of water being regulated or governed by the amount of gas generated; and it has for its primary object to provide improved means foravoiding the objectionable effects at the burners due to what is known as after production that is to say, to the generation of gas after the water has been shut oft by the supply already generated-and to obviate the wastage of the surplus gas thus generated without havingit produce undue pressure at the burner.

With these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter explained are attained, all as fully described with reference to the accompanying drawings,and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a side elevation, partly in section and partly broken away, of my improved apparatus as more especially designed for use on railway-cars or other Vehicles. Fig. 2 is a side elevation thereof, partly broken away, illustrating the apparatus in a form suitable for dwellings or the like. Fig. 3 is a detail side elevation thereof looking from another side. Fig. 4. is vertical sectional View of one of the automatic diaphragm mechanisms hereinafter described.

Like signs of reference indicate like parts in all the views.

A represents a generator or carbid-holder, which may be supported under the car by means of a frame or hanger n, which is secured in any suitable way to the structure of the carand has bearings for journals or trunnions e, projecting from the sides of the generator A, such bearings being vertically elongated to permit the generator A to be forced upwardly by means of a screw I, se-

cured in the bottom of the frame n and bearing against the bottom of the generatorA, so that the top of the generator may be pushed into firm contactwith a cap-plated, secured to the bottom of the car for hermetically closing the top of the generaton Arranged within the car or at some other suitable elevated position is a water-tank E, from the bottom of which extends a waterpipe a, provided with a controlling-cock W, which may be closed by hand when it is desired to shut the water off entirely. The lower end of this piped is connected with the generator A through the cap ct for supplying water to the cal-bid in the generator A, and interposed in the pipe a at a suitable point is a valve-housing y, in which is located an automatic cock, having operating key or lever u. This key to is connected by means of rod 0 with a weight g, which rests upon a flexible diaphragm arranged in a diaphragm-chamber V, whose bottom portion is connected by a pipe with the generatorA through the cap a, so that the gas generated in A may rise through pipe 70 and enter the diaphragm-chamber V and by thus acting upon the diaphragm 1) close the cock y more or less, according to the degree of pressure of the gas generated in A, and thereby govern the flow of water through pipe at accordingly. The rod 0 may be guided by means of a number of balls 0, arranged in a small cylinder 0 locatedin the upper part of the diaphragm-chamber V. The rod 0 may also be provided with a turnbuckle Z, whereby its length may be varied and the opening of the cock g gaged to a nicety. When it is desired to refill the carbid-holder A, cocks W and V located in the pipes 7a a, respectively, below the diaphragm-chamber V, are first closed and the screWIis then unscrewed and the carbid-holder let down until it may be tilted sufficiently for recharging.

13 represents a gas-holder which is supported under the car by means of straps n and connected to the pipe 70 by means of pipe 71: and a branch pipe 75 in which is located a cock k whereby when desired the flow of gas from the generator A may be entirely shut oif from the holder B. The pipe k is connected by a branch pipe k having stop-cock hr,

with the housing of an automatic valve y, the same in construction and operation as the valve 3 which has an operating key or lever a, connected by rod C with a weight (1, resting upon a diaphragm 19, arranged in a diaphragm-chamber V, all the same in construction and operation as the corresponding parts already described with reference to the diaphragm-chamber V and operating parts, the diaphragm-chamber V being provided with a small cylinder 0 in which are arranged a number of antifriction-balls c, which serve to guide the rod 0. The outlet of the automatic valve y is connected by means of a pipe 7c with another gas-holder B, which is supported under the car by means of straps 01 and this pipe 7c is also connected with the diaphragm-chamber V at a point below the diaphragm p by means of a branch pipe 25 The holder B is the reservoir from which the gas is drawn for use. Thus it will be seen that when the pressure in the auxiliary holder B rises to an abnormal degree, discharging into main holder B via pipes 7c, and It will raise the pressure in the latter holder to an abnormal degree; but before the quantity can become sufficient to produce any appreciable detrimental eifect at the burners the increase of pressure against the under side of the diaphragm p, reaching said diaphragm through the branch pipe U, will cause the automatic valve y to close and intercept communication between the pipe k and the pipe 70 which leads to the holder B, while communication between the holder B and the generator A will not be interrupted; but the increase of pressure in the holder B will nevertheless be communicated to the diaphragm 9 through the pipes 70' and k and 7t and the supply of water to the generator A thereby interrupted or entirely shut off at the automatic valve-cock y. Consequently the after production of gas or that quantity of gas which is generated by the water already admitted to the generator A after the supply has been shut off at the valve y will not be allowed to reach the holder B nor to pass on to the burnerswhile the pressure is above normal, nor, on the other hand, will it be allowed to escape into the atmosphere, but will be received and stored by the holder B until the pressure in the holder B has fallen below normal, whereupon the diaphragm 19' will release the automatic valve 3 and permit more gas to pass from the holderB to the holder B, the flow being continued until the pressure in holder B again reaches the normal degree, when the valve 11 will be again automatically closed by the pressure backing up into thediaphragm-chamber V through the branch connection 70 In the form of myinvention shown in Fig. 2 the holder A is secured to the plate a by means of set-screws d, which are adapted to clamp the plate a firmly against and close the top of the holder A. If desired, the pipes at and k may be provided with unions 1' 11, 10-

cated above the cooks w 10 so as to permit the holder to be disconnected without permitting the gas therein to escape. The gas-pipe k at a point just below the diaphragm-chamberV may be connected with the upper portion of the water-tank E by means of a valved pipe Q. I have shown the gas-holders B B arranged one above the other in this form of the invention, and the holder B is connected with the pipe 70 by means of a pipe 10 and a branch pipe 70 the upper end of the pipe 70 being connected to the automatic valve-housing 3 before described, and provided with the stop-cock 70 The valve-housing y is connected with the gas-holder B by pipe it, having cock 7t, and at a point below the diaphragm p by the pipe k which is provided with cock 70 and runs directly to the holder B. The two forms of the apparatus, however, operate in the same manner.

Having now described and ascertained my said invention and in what manner it is to be performed, I declare that what I claim is- 1. In an acetylene-gas apparatus the combination of a generator, a water-supply, a main gas receiver or chamber, a pipe connection between said water-supply and generator, an automatic cock in said pipe connection closed by the pressure in the generator, a pipe connection between the generator and said main receiver, an automatic cock in said .last pipe connection for closing communication between the generator and main receiver, and an auxiliary receiver connected with the last said pipe at a point between the last said cock and the generator and being otherwise disconnected from said main receiver, substantially as set forth.

2. In an acetylene-gas apparatus the combination of two collecting chambers or receivers B B, a generator having pipe connec= tion with the chamber B, a regulating stop-' valve in said pipe, the other of said chambers B, having communication with said pipe at a point between said valve and generator, a water-supply pipe having a regulating-cock connected with said generator, two similar regulating devices V V operatively connected with said cock and regulating-valve respectively and permanently subjected to the pressure of the generator and chamber B respectively and adapted to be actuated thereby to simultaneously close respectively the watercock and communication between the generator and chamber B when pressure in either of said chambers B B becomes abnormal, and to automatically open said cock and valve when the pressure falls below the normal and thereby reestablish communication between both collecting-chambers B B and the gener ator and the generator and water-supply, sub stantially as set forth.

3. In an acetylene-gas apparatus the combination of a gas receiver or chamber, a water supply, a generating tank or carbidholde'r having an opening for the introduction or removal of carbid, a cap through which In witness whereof I have hereunto set my hand in presence of two witnesses.
